REGULATING DEVICE FOR GAS OR VAPOR STOVES.

SPEGJEFICATION forming part of Letters Patent No. 691,019, dated January 14, 1902. Application tiled December 28, 1898. Serial No. 700,497. (Nc model.)

To all whom it may concern,.-

Be it known that I, GUsTAv TRESENREUTER, engineer, a subject of the Emperor of Germany, residing at N o. lnvalidenstrasse,l3er

5 lin, N., in the Empire of Germany, have invented certain new and useful Improvements in Regulating Devices lfor Gas or VaporBurners, of which the following is a specification.

This invention relates to a device by means 1o of which the gas issuing from gas-burners of all kinds may be exactly regulated. This is effected in accordance with my said invention by making the outlet-opening of pointed conical form which can only be opened or t5 closed gradually by means ot' a thin pointed part displaceable vertically.

In the accompanying drawings, Figure l is a vertical section of one form of the improved regulator. Fig. 2 is a detail view thereof,

zo and Fig. 3 is a vertical section of another form or modiiication.

In Fig. l the outlet c is closed by means of a pin d, the lower extremity of which forms a sharp point. This pin is guided above by 2 5 means of a short cylindrical guide-tube 7c, which is capable of vertical displacement within a tube h, arranged upon the burner d. This displacement is eiected by means of an oblique slot g, in which the arm f works.

3o The extremity c of this arm surrounds the pin d, while the outer extremity terminates in a knobf. It will readily be understood that by means of this simple arrangement when the knob f is displaced the point d will either leave the aperture c or enter the same, as the case may be. According to the extent of the lateral displacement of the arm f in the slot g the size of the outlet is regulated. In Fig. l the aperture is shown com- 4o pletel y closed, so that no gas can escape from the burner. In Fig. 2, on the other l1and,the aperture c is entirely free, so that the full quantity of gas is ableto issue. In the intermediate positions of the knob f the size of the aperture varies.

In the burner illustrated in Fig. l the tube h serves not only for guiding the pin d and its cylinder k, but also as a cylinder for mixing the gas issuing from the aperture c with 5o the air entering through the tube h in proximity to the opening of the burner. The mixture of gas and air burns with a blue flame in the known manner. In this form of burner the pin-point d performs a further and very important oiiice-that is to say, it serves also as a cleansing device for the aperture c. It

is well known that when the gas manufactured from liquid illuminant--such as petroleum, for example-is employed instead of illuminating-gas a line deposit, which usually 6o consists of a sticky coating, is formed upon theoutlet or burner aperturein consequence of the cooling which takes place. This coat may increase to such an extent as to completely close the outlet, and this outlet should consequently be cleansed from time to time.

In the present case this cleansing ofthe burner is effected by means of the point d each time the aperture is closed, owing to the fact that the point cZ/ penetrates and removes any ooat- 7o ing which may have formed.

The vertical displacement of the pin d may also be effected in otlierways, Fig. 3. If the tube 7o is prolonged downwardly upon one side and is there provided with a cross-piece j', through which a set-screwt'passes and bears against a projection t" from the tube h, thus limiting the rise of the pin d, the descent of the pin d is limited by its encountering the sides of the aperture c. Other means for ef- 8o fecting the vertical displacement of the pin cl may readily be devised.

The form of burner illustrated in Fig. 3 differs from that shown in Figs. l and 2 mainly owingr to the fact that the closing-pin dis replaced by a hollow rod or tine tube. The aperture c is thus never completely closed,- as even if the point of the pin d has entirely entered the conical aperture c gas is still able to escape upward through the small 9o tube d. This tube or hollow rod forms a pilot-burner. The arrangement is such that the gas issuing at the upper extremity d of the tube CZ is ignited by the flame burning upon the aperture between h and ic at the moment when the supply of gas to the dame proper is interrupted by the descent of the tube d. The small iiame which is so ignited at the aperture d then serves as an ignitionflame, and it continues to burn until the roo tube d is caused to rise out of the aperture o, whereupon the gas naturally follows the most ftube mounted on said burner-head, a guidetached to said guide-tube, and means for moving said rod and guide-tube to open and close the gas-outlet.

In testimony whereof I have hereunto Set I5 my hand, in presence of two subscribing witnesses, this 13th day of December, 1898.
